Description
Technical field
The invention belongs to new material and intelligent Manufacturing Technology field are and in particular to one kind prepares aluminium alloy using 3D printing
The method of section bar.
Background technology
Aluminium is a kind of argenteous metal, and it is low to have density, only 2.79/cm3, about steel, copper or brass density (
It is respectively 7.839/cm3, 8.939/cm3) 1/3.The features such as electric conductivity and thermal conductivity are good, plasticity is high, corrosion resistance is good, aluminium
Surface there is the reflectivity of height, radiation energy, visible ray, radiant heat and electric wave can be reflected by aluminium effectively, and anodic oxygen
Change and dark anodised surface can be reflexive or absorbefacient, the aluminium after polishing is in very wide wavelength model
There is in enclosing excellent reflectivity, thus there is various decorative uses and the purposes with reflection function.The chemical property of aluminium
Vivaciously, be easily combined with oxygen in atmosphere, surface forms the firm aluminum oxide film of one layer of densification, can protect inner layer metal not followed by
Continuous oxidation, therefore have fabulous stability in an atmosphere.Reserves in the Nature for the aluminium are very abundant, content in the earth's crust for the aluminium
For 7.45%, it is only second to oxygen and silicon, the reserves of China's bauxite are also at the forefront in the world, proved reserves have 6.3 hundred million tons, and it
It is a kind of metal with very strong reproducibility, its " green life power " is available for persistently playing.
Because the hardness of fine aluminium is less, so being difficult to use as structural material, the other in order to make full use of aluminium is excellent
Optimum energy, improves the mechanical strength of aluminium, typically by adding other metal ingredients, generates different types of aluminium alloy.Existing
In generation life, aluminium and aluminium alloy have been widely used in various industries.
Aluminium alloy has advantages below：
(1) density is little：Density is little to be had for the vehicles such as aerospace craft, ship, vehicle and building lightweight very much
Benefit, in communications and transportation, can greatly reduce oil consumption, can also save portage and processing charges simultaneously, reduces cost, industry,
The application in the fields such as building industry, civilian industry is more and more extensive.
(2) good corrosion resistance, weatherability：Aluminium and aluminium alloy can form one layer of firmly and fine and close, tool in an atmosphere
There is the oxide-film of good corrosion energy, be surface-treated by anodic oxidation, electrophoretic coating, powder spray etc., can carry further
The corrosion resistance of high aluminium.
(3) good machinability and dicoration：Aluminium alloy has good plasticity, can be processed into all size, shape
The product of shape, can generate the film layer of heterogeneity, different colours, have good dicoration by surface treatment.
(4) good thermal conductivity：The thermal conductivity of aluminium alloy is about the 50.6% of copper, and this is to manufacture heat exchanger, steaming
Send out device, heating electrical appliance, cooking utensils, and the cylinder cap of automobile is highly beneficial with radiator.
(5) good malleability：Aluminium alloy can be forged into intensity height, shape and forging various in style, they
The range of choice that final part forges design standard is very wide in range.
(6) good solderability：Aluminium alloy can be connected with method miscellaneous, including melting welding, electric resistance welding, hard solder, soft
Weldering, bonding and the mechanical means such as riveting and bolting etc.
(7) high recyclability：The characteristic of secondary aluminium alloy and primary aluminium alloy almost do not have difference, and this point makes aluminium close
Gold becomes the favorite of environmentalist, and the feature of environmental protection is fairly good.
(8) aluminium alloy has high specific strength, specific stiffness, fracture toughness and fatigue strength, replaces ferrous materials big with it
The big weight mitigating zero component, increases the stability of structure.As a kind of structural timber, in liquid missile, carrier rocket
It is used widely with aircraft, also quite varied in other sector applications.
(9) special aluminum alloy has high resistivity, and these alloys can be used for as in the motor of high torque (HT).
According to purposes, aluminium alloy generally will be made into various different section bars, and current aluminium alloy extrusions is all to adopt mould
Fashion of extrusion supports, in order to manufacture different types of section bar it is necessary to produce the mould of section bar in advance, thus manufacturing cost
Height, the manufacturing cycle is long, very weak to the adaptability to changes of demand.In addition, present aluminum alloy materials are all to be made, quenched by melting, refining
The techniques such as fire, solid solution, Ageing Treatment manufacture, uncontrollable to the distribution consistency degree of the various elements of component alloy, right
The composition of microstructure of the alloy also cannot precise control, thus the performance of prepared alloy also just cannot be accomplished to be precisely controlled.
